> Particulates issued from tailpipes can aggravate asthma and heart disease and increase the risk of lung cancer and heart attack. Globally, they are a leading risk factor for premature death.

Minor nitpick, but tailpipes aren't the primary source of emissions. The study is about PM2.5[0]. which will chiefly be tires and brake pads. Modern gasoline engines are relatively clean, outside of CO2, though diesel engines spit out a bunch of bad stuff.

How do EVs fare in this regard? Brakes are used significantly less, but the additional weight from the batteries chews through tires faster.

Why does everyone immediately pivot to EVs on this subject, instead of (looks around) gargantuan SUVs and trucks everywhere, due to peculiarities of US policies regulating SUVs more leniently than cars on fuel efficiency?

Because a lot if EV buyers are interested in the environmental impact of their purchase?

I say this as someone who owns an electric scooter and whose next car will be an EV—the sales pitch for EVs right now is basically pay more (especially now that the tax credit is gone) to have a worse time and maybe eventually claw some of it back over the lifetime of the car in fuel savings. The environmental impact is the pro in the pro con list. So if that doesn't pan out, or doesn't pan out enough it's going to be a tough sell.

Just the cost to get my garage outfitted with a charging port is about to be in the thousands because it requires me to replace the entire breaker panel. Now this is a me problem because that panel is ancient but it does add to the total cost of "doing this" and going EV.

You likely don't need to install a special charger or breaker panel. A regular 120V wall outlet will give probably give you 30+ miles of range just charging overnight. If your commute is longer, you might want a better charger, but don't let someone upsell you on a high-speed charger if your average daily travel is under 30mi and 90%ile under 100mi.
